AAA estimates that one in three Americans will be traveling more than 50 miles this holiday season – and while many people will be hitting the roads - millions will be taking to the sky. 

December 23rd is considered one of the biggest travel day s of the year, but at Harrisburg International Airport the crowds are slightly down. 

Scott Miller, spokesperson for HIA said, “This year it’s down a little verses a year ago because of the increased cost of energy and fuel.” 

While air traffic is estimated to be down roughly 10 percent from last year, in some cases it’s a good thing.

Danylle Ritchie of Manheim and her two children were waiting anxiously at the arrival gate on Friday for the return of their dad and husband.

“He called from Atlanta and said he was on time so I was pretty excited,” said Ritchie.

So this early holiday home coming couldn’t come soon enough.

“My son was in the car about a hour early – buckled in and ready to come,” said Ritchie.

According to study conducted by AAA , 2011 will be the second time in a decade that more than 90 million people will be traveling during this time period.
